MACHINE.

SPECIFICATION forming part of Letters Patent No. 599,505, dated February 22, 1898.

Application filed April 26, 189 7.

To CLZZ whom it may concern.-

Be it known that I, FRANK A. JABERG, a citizen of the United States, residing at New Philadelphia, in the county of Tuscarawas and State of Ohio, have invented a new and useful RiVeting-Machine, of which the follwing is a specification.

This invent-ion relates to riveting-machines adapted for applying hollow rivets; and the object in view is to provide a simple, cheap, durable, and efficient device for this purpose, and in which objects of different thickness may be riveted together without requiring an adjustment of any of the parts of the machine.

A further object of the invention is to pr0- vide in the machine a receptacle in which the rivets to be used may be stored.

With these and other objects in view the invention consists in the several details of construction and combination of parts hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of the riveting-machine constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section through the jaws, the handles being broken away. Fig. 3 is a plan view of the machine. Fig. 4. is a similar view of a portion of the lower jaw. Fig. 5 is a detail plan view of the die-face in the upper jaw.

Similar referencediumerals indicate similar parts in the several figures.

1 and 2 represent, respectively, the upper and lower handles, and 3 and 4. the upper and lower jaws. The opposing faces of the jaws are straight and arranged parallel to each other. The lower jaw t is formed integrally with the handle 1, a vertical sleeve portion 5 being interposed between them. The upper jaw 3 is provided with an arm 6, arranged at a right angle to it, and this arm 6 extends through the sleeve 5 and is pivoted at its lower end between spaced ears 7 at the front end of the handle 2. The sleeve 5 is provided in its front face with a slot 8, which extends from its upper end down to the upper face of the jaw a and is for the purpose of permitting the jaw 3 to have a reciprocating movement toward and away from the jaw 4. The upper handle 1 is pivoted between the upper ends Serial No. 634,058. (No model.)

of a pair of links 9, and the handle 2 is pivoted between their lower ends, and it will be seen that by this construction if the handles 1 and 2 are moved toward or away from each other the jaws 3 and 4: will be given a similar movement and that the opposing faces of the jaws 3 and 4 will always maintain a true parallel relation to each other.

The front end of the jaw 4 is rounded, as indicated at 10, and is connected to the main portion of the jaw by a narrow neck 11. A sleeve 12 is fitted over the rounded end of the jaw, and this sleeve is provided in its rear face with a vertical slot 13 to receive the neck 11. The sleeve 12 is closed at its lower end and provided with a transverse slot 14, into which the upturned end 15 of a spring 16 enters. This spring is secured at its rear end to the lower face of the jaw 4: by means of a set-screw 17. The normal tendency of the spring 16 is to force the sleeve 12 upwardly, and when in its normal position the upper end of the sleeve 12 will extend above the upper face of the jaw 4. This sleeve is intended as a guide and support for the rivet to keep it in proper position while being applied to the objects to be riveted together. The head of the rivet will be supported upon the upper face of the rounded end 10 of the jaw, and the tubular shank of the rivet will extend upwardly within the sleeve 12.

18 indicates a die which is supported in the forward end of the jaw 3 and is in axial alinement with the rounded end 10 of the jaw l. This die is provided with a shank 19, which extends through the jaw 3 and is burred at its outer end in order to securely hold the die in position. The die is intended to split and spread the open end of the tubular shank of the rivet, and in order to accomplish this the die-face is projected at its center to form a pyramidal boss 20 and near its periphery to form spurs 21, concave turningguides 22 being arranged between the apex of the pyramidal boss and said spurs. The apex of the boss enters the open end of the hollow shank of the rivet, such as that shown in section at 23 in Fig. 2, and when pressure is exerted upon the jaws the open end is split by the several angles of the boss, and the ends thus formed are flared and turned back upon the object being riveted and caused to enter the surface thereof and thus conceal or countersink the edges.

The arm 6 of the jaw 8 is cored or hollowed out to form a receptacle 24, in which the rivets may be stored, and the open end of this receptacle is closed by a lid 25, which is pivoted on a screw 26, secured in the jaw 3.

In operation the rivet is placed within the sleeve 12 with its head resting upon the upper face of the rounded end 10 of the lower jaw 4, and the objects to be riveted are inserted between the open jaws. By forcing the handles together the jaws 3 and at will be moved toward each other and the tubular shank of the rivet will be first forced through the objects to be riveted together, and the die-face 18 will then split and spread the open end of the shank and thereby effect the riveting. During the riveting process the sleeve 12 will be moved downwardly over the rounded end 10 of the jaw 3 against the force of the spring 16, and as soon as the parts that have been riveted together are removed from between the jaws the spring 16 will return the sleeve 12 to its normal position ready for the reception of another rivet.

This machine is especially intended for mending harness, belts, bags, or similar articles, and, as will be seen, objects may be riveted together without regard to their thickness provided,"of course, the objects are not too thick to be inserted between the open jaws, and that no adjustment of any part of the machine is necessary. As the arm 6 is confined within the sleeve 5, it will be apparent that the jaws 3 and 4: will always maintain their parallel relation to each other during their movement toward or away from each other. The receptacle 24 is an important addition to machines of this character, as the rivets will always be accessible.

It will be understood that changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is- 1. In a riveting-machine, the combination of a jaw integral with its handle and having a sleeve portion arranged between them at a right angle to said jaw, a second jaw arranged parallel with the first jaw and having-an arm projecting at a rightangle from its rear end, said arm extending through said sleeve, a handle pivoted to the lower end of said arm, and a link pivoted at its opposite ends to the respective handles in rear of the jaws, substantially as described.

2. In a riveting-machine, the combination of a jaw integral with its handle and having a'sleeve portion arranged between them at a right angle to the jaw, said sleeve having a slot in its front face, a second jaw arranged parallel with the first jaw and having an arm projecting at a right angle from its rear end, said arm extending through said sleeve and the jaw extending through said slot, a handle pivoted to the lower end of said arm, and ,a link pivoted at its opposite ends to the respective handles in rear of the jaws, substantially as described.

3. In a riveting-1nachine, the combination of reciprocating jaws, the outer end of one jaw being rounded and connected to the main body of the jaw by a narrow neck, a sleeve fitted on the rounded end of said jaw and pro vided with a longitudinal slot for the reception of the said neck, said sleeve being closed at its lower end, a spring secured at one end to the under face of the jaw and engaging with its free end the closed end of said sleeve, and a splitting and spreading die rigidly secured to the end of the other jaw in axial alinement with the rounded end of the firstnamed jaw, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

FRANK A. JABERG.
